We have completed our analysis of the GMAT Official Guide Quant Review 2nd Edition.  Of the 300 questions, 74 (25%) are new to the 2nd edition.

These 74 problems did not break dramatic new ground in terms of tested material.  The bottom line is that the 2nd Edition is a nice add-on, but you should still feel fine about studying from the original Quant Review Guide if that’s what you’ve got handy.  For a complete list of the new problems and a detailed breakdown by topic, click here.
